Hewlett-Packard Co has joined the battle to try to persuade IBM Corp System/36 users to convert to Unix, and has enlisted Raconix Corp to the cause. Raconix has a program called U/3X designed to convert System/3X and AS/400 family software to run under the HP-UX implementation of Unix. Under the relationship, Raconix will supply its U/3X software, conversion training, support and on-line documentation and Hewlett-Packard will provide marketing and technical support through its sales force and network of value-added resellers. Raconix’s re-engineering technology is claimed to convert 36 code into source code for a Unix system in a matter of days and converted applications can incorporate a user interface that is the functional equivalent of the 36 and an optional developers package enables continued systems development in the 36 environment. No word on prices, or whether the facility is limited to RPG II applications.
